Copper Laser Welded Finned Tubes

Laser Welded Finned Tube Product Description:

The finned tube provide by us is laser welding type, which is different from the ones through HF Welding and Wrapping method. The fin (flat sheet material) is smoothly welded onto the outer surface of a soft seamless plain tube. The technology offers 99% to 100% fully welded condition. So the fin and the tube are integrated and inseparable, which avoids the heat resistance between fin and tube, and optimizes heat exchange efficiency. Based on this technology, fully welded Stainless Steel Fin Tube with high fin is possible, which can survive much more severe working conditions than other materials like copper, aluminum . Also it, on the other hand, shows several unique features such as enhanced physical structure, resistance to vibration, anti-corrosion ability, and long service life, etc.

Laser Welding Fin Tube Manufacturing Process:

The fin strip is welded continuously and spirally wound onto a polished bare tube. And the tube and fins are bonded together by using advanced laser welding technique.

Laser Welded Finned Tube(Stainless Steel Welded Pipes) Properties:

100% welding between fin and tube without using filler material.

No impurity of the weld seam, as the Laser-welding is carried out under a protective atmosphere

Different materials for fin and tube

Uncomplicated bending and coiling of the finned tube

No material deformation due to a small heat affected zone and thin weld seam, only slight microstructural change in tube and fin
